Injector Offset question
Im running accel 24's and have the offset data from their website, but the chart jumps and leaves holes in the correction table on the ARAP bin im running. Is there a more complete data set out there? I did some searching and did not come up with anything. Thank you

Re: Injector Offset question
I'm running Bosch 30 pounders in my Holley HP EFI. ....I had the same issue, and yes...linear interpolation. My method was a little unorthodox, but it worked. Remember when your math teacher said you'll use this everyday? First time I've have to graph a curve since college, lol.

Re: Injector Offset question
Here's what I get with their datasheet...

Only goes from 6.4 to 16V, but the reality is you shouldn't be operating anywhere outside of 13V to 15V anyway...

Re: Injector Offset question
If you graph the curve in Excel then you can let Excel curve fit and show the equation. Might be a better fit than linear interpolation.

I would agree that if you had the curve as opposed to a line between given points, that would be the way to go. Don't use Excel much and didn't know you could do that!

its been my experience that you get close enough with linear interpolation.

Yes, probably fine inside normal operating range.
